The thread title is mistaken, I have 4 questions. Sorry guys :(
Hi there. I'm new here and I am new to fish care. I decided to get a betta because I have wanted to learn how to care for fish and bettas are apparently a good starter fish. Bettas are beautiful and I always feel sorry for them when I see them in their tiny containers at the pet store. I bought a 5 gallon tank, one decoration and multiple fake plants for my fish to hide among. My younger brother is an accomplished fishkeeper and he told me to let the tank adjust for two weeks before buying my fish. I just can't wait to bring one home (excitement!). My brother has kept many fish, but never a betta, so I decided to come here with a few questions I hope some of you will answer.
1. The tank I bought has an incandescent bulb. My brother told me I would not need a heater because of this, but I read somewhere that water temp can drop by more than 8 degrees at night and I don't want the little guy to get cold. Should I get a heater to turn on at night?
2. I want my fish to have the healthiest diet possible. I am catastrophically allergic to shrimp and have heard that frozen brine shrimp can cause reactions in some people. What other kinds of food can I give him? If possible, I plan to feed him a variety of good stuff.
3. Another feeding question: I read that blood worms carry parasites. Should I avoid them altogether, or is there a type that is less likely to make a fish sick?
4. How likely is it that my betta will get sick? Is there anything I should have on hand to treat a potential illness?
I have many more questions, but I don't want to be too difficult
. Thanks in advance!
